If it can’t, specimen can be kept in -20 ℃ to preserve, Avoid repeated freeze-thaw cycles. 7. Can’t detect the sample which contain NaN3, because NaN3 inhibits HRP active. Assay procedure 1. Add standard: Set Standard wells, testing sample wells. Add standard 50μl to standard well. 2.add sample:Set blank wells separately (blank comparison wells don’t add sample and HRP-Conjugate reagent, other each step operation is same). testing sample well. add Sample dilution 40μl to testing sample well, then add testing sample 10μl (sample final dilution is 5-fold), add sample to wells , don’t touch the well wall as far as possible, and Gently mix. 3.add enzyme:Add HRP-Conjugate reagent 100μl to each well, except blank well. 4.Incubate: After closing plate with Closure plate membrane ,incubate for 60 min at 37℃. 5.Configurate liquid: 20-fold wash solution diluted 20-fold with distilled water and reserve. 66.washing:Uncover Closure plate membrane, discard Liquid, dry by swing, add washing buffer to every well, still for 30s then drain, repeat 5 times, dry by pat. 7.color:Add Chromogen Solution A 50ul and Chromogen Solution B to each well, evade the light preservation for 15 min at 37℃ 8.Stop the reaction:Add Stop Solution 50μl to each well, Stop the reaction(the blue color change to yellow color). 9.assay:take blank well as zero , Read absorbance at 450nm after Adding Stop Solution and within 15min. 7Important notes 1. The kit takes out from the refrigeration environment should be balanced 15-30 minutes in the room temperature, ELISA plates coated if has not use up after opened, the plate should be stored in Sealed bag. 2. washing buffer will Crystallization separation, it can be heated the water helps dissolve when dilute . Washing does not affect the result. 3. add Sample with sampler Each step, And proofread its accuracy frequently, avoids the experimental error. add sample within 5 mins, if the number of sample is much , recommend to use Volley . 4. if the testing material content is excessively higher (The sample OD is bigger than the first standard well ),please dilute Sample (n-fold), Please diluente and multiplied by the dilution factor.(×n×5). 5. Closure plate membrane only limits the disposable use, to avoid cross-contamination. 6. The substrate evade the light preservation. 7. Please according to use instruction strictly, The test result determination must take the microtiter plate reader as a standard. 8. All samples, washing buffer and each kind of reject should according to infective material process. 9. Do not mix reagents with those from other lots. 8Calculate Take the standard density as the horizontal, the OD value for the vertical ,draw the standard curve on graph paper, Find out the corresponding density according to the sample OD value by the Sample curve, multiplied by the dilution multiple, or calculate the straight line regression equation of the standard curve with the standard density and the OD value ,with the sample OD value in the equation, calculate the sample density, This chartis for reference only multiplied by the dilution factor, the result is the Assay range 0.25 ng/mL - 8 ng/mL Sensitivity The minimum detectable dose is typically less than 0.1 ng/mL Storage and validity 1.Storage: 2-8℃. 2.validity: six months. 其他產品介紹: G&VS10105 干細胞成脂分化潛力定性染色試劑盒 20/100次 現G&VS10106 干細胞成脂分化潛力比色法定量檢測試劑盒 20/100次 現G&VS10001.3 胚胎干細胞(ES)凍存試劑盒 50次 G&VS10281 胚胎干細胞分化定性檢測試劑盒 20次 G&VS10282 胚胎干細胞未分化定性熒光檢測試劑盒 10次 G&VS10283 胚胎干細胞內胚層(endoderm)細胞分化熒光檢測試劑盒 10次 G&VS10284 胚胎干細胞中胚層(mesoderm)細胞分化熒光檢測試劑盒 10次 G&VS10285 胚胎干細胞外胚層(ectoderm)細胞分化熒光檢測試劑盒 10次 G&VS10286 胚胎干細胞心肌細胞(cardiomyocyte)定向分化試劑盒 5次 G&VS10287 胚胎干細胞神經細胞(neuron)定向分化試劑盒 5次 G&VS10288 胚胎干細胞內皮細胞(endothelial)定向分化試劑盒 5次 G&VS10289 胚胎干細胞造血細胞(hematopoitic)定向分化試劑盒 5次 G&VS10290 胚胎干細胞胰島細胞定向分化試劑盒 5次 G&VS10322 腫瘤干細胞熒光定性檢測試劑盒 20次 現G&VS10490 干細胞成骨分化潛力比色法定量檢測試劑盒 20/100次 現G&VS10491 干細胞軟骨細胞分化潛力比色法定量檢測試劑盒 20/100次
